Enforcing Dependency Rule With Custom Detekt Rules

Clean Architecture is a much-discussed topic in recent years not only in the Android community. You can find many articles about it and most of them are devoted to an explanation and implementation of the Dependency Rule, which is the basis of the Clean Architecture. Implementing the Dependency Rule is quite easy but it is also really easy to violate it and it can be really hard to uncover that on the code review. It would be possible to control it better using `package private` visibility or divide app layers properly to separate modules. The problem is that we do not have `package private` visibility in Kotlin and layer modularization does not have to be a good or preferred architecture for our app. But don’t worry! We can use help from the static code analysis tool called detekt and I am going to show you how in this article. I expect that you already know and understand Clean Architecture including the Dependency Rule. If you don’t, I recommend this great article from Mario Sanoguera de Lorenzo. (more…)

Micro services in the agency development?

As you might know from our previous blogs, our primary language for writing backends is Node.js. One of the main reasons why we have chosen this technology was that we started to feel the limits of all the other classic monolithic applications, where all the basic logics, renders, request processing and so on were done in one codebase. It was rather limiting not only technologically, but also from the human resources point of view. Also in the area of our PHP “ends”, according to our recently finished projects, we used to divide the final depicting layers into the individual thin client written in React. But we wanted to go even further; dividing the backend into multiple smaller and self-maintaining parts.

blog post about React Native

AirBnB is done with react. What would Ackee say?

You might have read my previous series of blogs on React Native. And I feel sad, that it remained a bit misunderstood. By all means, React Native is an interesting technology; I just meant to point out its weaknesses and a way it’s being misused by the agencies around us. And as we see now after a while, according to AirBnB and Udacity who stopped using react for their app development, I was right.

Ackee publishes cookbook

What? Ackee and cooking? Well, not entirely, even though we did show we knew our way around the kitchen at the #dnesnekodim event. However, considering we feel better behind the keyboard, our cookbook will not be about food but about programming. Read about how we prepare the best applications on the Czech scene, what tools we use, as well as all of our secret procedures. (more…)
